Display apparatus

Abstract

Disclosed herein is a display apparatus. The display apparatus includes a display module configured to display a screen, a frame configured to support the display module, a magnetic coupling device configured to couple the frame to the display module by pulling the display module toward the frame by using the magnetic attraction force, and a separation prevention device configured to mechanically prevent the display module from being separated from the frame and configured to be operated by the magnetic force.

What is claimed is: 
     
       1. A display apparatus comprising:
 a frame; 
 a display module comprising at least one substrate on which a plurality of light emitting elements is mounted, and a bracket to which the at least one substrate is attached; 
 a magnetic coupling device configured to couple the frame to the display module by pulling the display module toward the frame by using a magnetic attraction force; 
 a latch; and 
 a magnet mounted to the latch, wherein
 the latch and the magnet are rotatable together as a same body between a locking position where the latch mechanically prevents the display module from being separated from the frame and an unlocking position where the latch allows the display module to be separated from the frame, in accordance with an external magnetic force applied to the magnet, and 
 the latch and the magnet are configured so that,
 when one of an N pole and an S pole of an external magnet is moved to a front side of the display module, the external magnetic force is applied to the magnet to thereby cause the latch to be rotated from the unlocking position to the locking position and 
 when the other of the N pole and the S pole of the external magnet is moved to the front side of the display module, the external magnetic force is applied to the magnet to thereby cause the latch to be rotated from the locking position to the unlocking position. 
 
 
 
     
     
       2. The display apparatus of  claim 1 , further comprising:
 a catch fixed to the display module, wherein the latch is configured to be engaged with the catch when in the locking position and to be disengaged from the catch when in the unlocking position. 
 
     
     
       3. The display apparatus of  claim 2 , further comprising:
 a first magnetic member installed in the bracket to fix the latch in the locking position by a magnetic attraction force between the first magnetic member and the magnet mounted to the latch. 
 
     
     
       4. The display apparatus of  claim 3 , wherein
 the first magnetic member comprises a coupling member configured to fix the catch to the bracket. 
 
     
     
       5. The display apparatus of  claim 1 , further comprising:
 a second magnetic member installed in the frame to fix the latch in the unlocking position by a magnetic attraction force between the second magnetic member and the magnet mounted to the latch. 
 
     
     
       6. The display apparatus of  claim 1 , further comprising:
 a shaft configured to couple the latch to the frame and to form a rotational axis of the latch. 
 
     
     
       7. The display apparatus of  claim 2 , wherein
 the catch has a locking hole, 
 the latch comprises a locking protrusion, and 
 the latch and the catch are configured so that, when in the locking position, the locking protrusion is inserted and locked in the locking hole. 
 
     
     
       8. The display apparatus of  claim 2 , wherein
 the catch is fixed to a back surface of the bracket. 
 
     
     
       9. The display apparatus of  claim 1 , wherein
 the frame has a rectangular frame shape comprising a vertical frame and a horizontal frame and 
 the latch is mounted on the vertical frame. 
 
     
     
       10. The display apparatus of  claim 9 , wherein
 a rotational axis of the latch is in parallel to the horizontal frame. 
 
     
     
       11. The display apparatus of  claim 1 , wherein
 the magnetic coupling device comprises a plurality of magnetic coupling devices installed at corners of the frame, and 
 the latch comprises a plurality of latches installed among the plurality of magnetic coupling devices, and 
 the magnet comprises a plurality of magnets mounted to the plurality of latches, respectively. 
 
     
     
       12. A display apparatus comprising:
 a frame; 
 a display module coupled to the frame by a magnetic force; 
 a catch installed on a back surface of the display module; 
 a latch installed in the frame; and 
 a magnet mounted to the latch, wherein
 the latch and the magnet are rotatable together as a same body between a locking position in which the latch is engaged with the catch and an unlocking position in which the latch is disengaged from the catch, in accordance with an external magnetic force applied to the magnet, and 
 the latch and the magnet are configured so that,
 when one of an N pole and an S pole of an external magnet is moved to a front side of the display module, the external magnetic force is applied to the magnet to thereby cause the latch to be rotated from the unlocking position to the locking position and 
 when the other of the N pole and the S pole of the external magnet is moved to the front side of the display module, the external magnetic force is applied to the magnet to thereby cause the latch to be rotated from the locking position to the unlocking position. 
 
 
 
     
     
       13. The display apparatus of  claim 12 , wherein
 the display module comprises a bracket, and at least one substrate attached to a front surface of the bracket and provided with a plurality of light emitting elements mounted on the at least one substrate. 
 
     
     
       14. The display apparatus of  claim 13 , further comprising:
 a first magnetic member installed in the bracket to fix the latch in the locking position by a magnetic attraction force between the first magnetic member and the magnet mounted to the latch, and 
 a second magnetic member installed in the frame to fix the latch in the unlocking position by a magnetic attraction force between the second magnetic member and the magnet mounted to the latch. 
 
     
     
       15. The display apparatus of  claim 12 , wherein, when in the locking position, the display module is mechanically prevented from being separated from the frame due to the latch being engaged with the catch.
